The censored bar was on purpose, the bleeping of any reference to Muhammed was done my Comedy Central. While it wasn't intentional, I laughed my ass off near the end of the episode when they're giving their speeches and saying how they all learned a lesson but Comedy Central bleeped it. It was 3 long bleeps. It was just so absurd and ridiculous I couldn't help but laugh.
From what I read online, the "lesson of the episode" didn't even mention Muhammed. So there was no point in bleeping that whole minute.
